DETROIT, MI -- Hours after Detroit Police Chief James Craig held a news conference telling reporters 12-year-old Charlie Bothuell V could be the victim of a homicide, investigators located the missing boy behind a barricade in the basement of his father's home, WDIV, Channel 4 News reports.

Charlie Bothuell V was last seen leaving his home in the 1300 block of Nicolet Place in Detroit about 9 p.m. June 14.

"Charlie's father stated that Charlie was working out when he stopped to go to the bathroom and never came back," Detroit police said in a statement announcing the boy's disappearance.

The boy's 45-year-old father, Charlie Bothuell IV, described his son as an intelligent lover of sports, especially the Detroit Tigers the NBA's Oklahoma City Thunder, who has an impressive singing voice, is learning piano and dreams of playing professional baseball.

Bothuell IV, a father of four including his missing son, appeared on the nationally broadcast "Nancy Grace Show" on HLN TV Tuesday night and was expected to make a second appearance Wednesday.

The Federal Bureau of Investigation and Detroit police have launched large-scale search for Charlie in recent days.

FBI officials told the father more than 40 law enforcers with a half-dozen K-9 handlers searched for the missing boy leading to a park along Lafayette near the boy's home where he lived with Bothuell IV and his stepmother.

Craig said, as with any missing persons case, we're "certainly looking at close family members first."

Both parents were asked to submit to polygraph tests. The father submitted to a test performed by the FBI with the results proving inconclusive; the stepmother refused, Craig said.
